Survival via long spread in the long-range contact process

Let q(t),q(x),p(0,1)q^{(t)},q^{(x)},p\in(0,1) be given, and let α>1\alpha>1. The long-range contact process (LoRaC) is the percolation model described in the paper, with edges whose length distribution has power-law parameter α\alpha. Survival via long spread. There exists αc>1\alpha_c>1 such that, for every α(1,αc)\alpha\in(1,\alpha_c), the LoRaC percolates. This conjecture asks whether survival can result from infecting sufficiently many houses rather than from infections persisting for a long time; it is presented as an open question, with a renormalisation argument suggested but not supplied.
